Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes

Advanced Functional Materials, EarlyView.
Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.

Innovative Seismic Strengthening of Reinforced Concrete Frames with U-Shaped Precast Concrete Wall Panels: Experimental Performance Assessment

Buildings
Many existing reinforced concrete (RC) frames with brick infill walls are vulnerable to earthquake damage, particularly when the walls contain window openings that reduce the lateral resistance.

Study on the Nonlinear Behavior of Strengthened RC Frames using Steel Prop and Crub in Connections and Strengthening of Beam and Column [PDF]

مجله مدل سازی در مهندسی, 2016
One of useful methods for strengthening for reinforced concrete frames, is to use steel prop and crub in connections, alone or combined with beam's revival steel sheets and column jacketing with steel sheets or profiles. In this paper, after modeling and

Seismic Retrofitting of RC Frames with RC Infilling [PDF]

, 2012
The effectiveness of seismic retrofitting of multi-storey multi-bay RC-frame buildings, by converting selected bays into new walls through infilling with RC, was studied experimentally at the ELSA facility at JRC, Ispra, and the results are reported here.

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

Advanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

The Non-Linear Behavior of Mixed Reinforced Concrete–Steel Frames under Strong Earthquakes

Engineering Proceedings, 2023
Mixed building frames constructed using reinforced concrete (RC) in the lower stories and structural steel in the higher ones meet great scientific interest as forming a common and often constructed building type. However, the current seismic regulations

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

Advanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

Experimental Study on Seismic Behaviour of RC Frames with Different Infilled Masonry [PDF]

, 2019
Six 1/2 scaled, single-storey, one-bay frame specimens were tested in this study to investigate the seismic behavior of masonry infilled reinforced concrete (RC) frames subjected to lateral loading. The variables investigated include types of masonry and

Numerical Analysis on the Collapse of a RC Frame

Mathematical Modelling in Civil Engineering, 2016
Abstract This paper focuses on the collapse analysis of a planar RC frame. This research is based on an experimental study presented in the literature. The analyses are conducted using a dedicated software based on the Applied Element Method. This numerical method is able to model accurately all the structural behaviour stages leading up
